The present? invention relates to agricultural implements generallyand'more particularly to an attachment which ma be mounted on the drawbar ot a conventional 45 or any suitable typle of tractor and has meansthereon for t e. reception of digging I imX ements and the like. v 'veryimportant object of the invention is to provide an attachment of thisnature 10 which is exceeding] adaptable for use as a i lister cultivatoran the like,

Another very important object of the invention is the" revision of anattachment of this nature. inc udin'g a marking implement which may beeasily and uickly adjusted to extend to'either side of t e tractor.

' Another very important object of the in-' vention resides in themounting of the attachment on a pivoted draw bar of a tractor 2'0 sothat said draw bar maybe lifted or lowered for the purpose of adjustingthe dig-' elements on the attachment mrelation Y g g to e ground.

Another very important object of the 1nvention resides in the provisionofan attachment of this nature which is exceedingly simple in itsconstruction, strong, durable, inexpensive to manufacture ears tomanipu- 1 late, attach or detach and ot erwise well so-adagied to thepurpose for which it is des1 ith theabove and numerous other objects inview, 'as willappear-as the descrip tion proceeds, the invention residesin car-- tain novel features of construction, and in the combination andarrangement of parts as will be hereinaftermore fully described andclaimed. a I In the drawings- 'j k Figure 1 is a top plan view fofvthe-attachment showing the same in association with a conventional formof tractor.

Referring to .the drawings in detail, it will be seen that the letter Tdenotes generally a tractor of a well known type to which my attachmentis particular] ada table.

Re erring in detail to theattachment it will be seen that the numeral 5 denotes an elongated angleiron beam substantially L- shaped in cross section and as will bereadily apparent from Figure 4, it is.

to have this particular bolt piercing the bight of the U-shaped drawbar..

A bracket 9 has its lower end attached as at 10 under the seat spring 11and extends rearwardly of the seat being pressed and terminating at itsupper end in an extension 12 disposed obliquely to the medianlongitudinal dimension of the tractor so that a casting 13 may beattached thereto. A brace rod 14 is attached as at 15 to the bracket 9and tern'iinates in a fork 16 having aperturcd cars 17 for receiving twobolts 18 of the cap C over the differential of the axle housing A. Alever 19 is pivoted intermediate its ends to the casting 13 and has adog for association with teeth provided on the casting so that the levermay be held in dif- A chain 20 is attached, to one end of the lever andto the bight ortion of the tractor. It will thus be seen t at b'yswinging the lever 19 the draw bar and the beam 5 maybe lowered orraised. I prefer to connect a spring 22 with an intermediate portion ofthe beam 5 as at 23 and with a portion of the casting 13, said springbein tensioned to assist in the raising of the eam and draw bar andimplements attached thereto, it being realized that the total weight ofthe assembly will be such as to make this spring very desirable althoughnot necessary. to the beam 5 as at 25 to the right of the center thereofand rises therefrom and inclines forwardly to terminate below and forwardly of the seat so that the person driving the tractor may maintainhis foot on the plate 26 at the upper end of the rod for a purpose whichwill be explained later.

' In the accompanying drawings, I have shown one practical example ofthe utility Referring to this example in detail it will be seen thatletters B denote one piece busters having the usual break foot pieces 27mo inted on clamp sleeves 28 which may be engaged with the center andthe two adjacent stub bars 7. On the end stub bars 7 there are laced thesleeves 29 of yokes 30, said sleevesloeing held tlfihtly in lace by setscrews 31 or in any 0t er suita le manner. By referring particularly toFigure 7 it will be noted that a- .stud bolt 32 1S drilled or otherwisefixed in the up er end of the foot piece 27 of the center buster B. Abeam 33 has one end thereof rovided with a flat apertured extension 34or reception of the stud bolt 32. It is to be noted that the aperture inthe extension'34 is larger than the diameter of the bolt so that thebeam may be rocked and pivoted thereof, The extension is held againstaccidental displacement in any suitable manner such as by nut and washer35. On the other extremity of the beam 33 there is journaled a diskmarker 36. Intermediate the ends of the beam 33 there is provided a Arod 24 is attachedhook 37. A chain 38 is engaged at one end with thehook 37 and .at its other end with one of the bolts 39 which hold therear clamps 10 in place. This chain 38 is sufficiently long to allow thebeam 33 to extend to one side of the tractor and rearwardly at an acuteangle to the beam 5. present instance the length of the beam 33 issufficient so that when positioned as just described and as shownclearly in Figure 5. the distance from the right hand buster to thefurrow dug by the marker 30 is equal to the distance between the rightand left hand busters. It will thus be seen that the center buster, whenthe tractor is turned around may be run in the furrow dug by the markerelement 36. In turning the tractor around the operator sitting on theseat lifts up on the chain 38 to place the beam 33 in the adjacent yoke30. The tractor is then turned around to place the center buster in thefurrow dug by the marker and then the marker isswung to the other sideof the tractor and the chain is engaged with the other bolt 39. In otherwords the marker element is changed from the right hand side of thetractor as shown in Figure 1 to the left hand side thereof.

It is preferable to provide two chains 45 engaged at one end with eyebolts 46 and at their other ends to elements 47. These chains take theplace of the ordinary brace rods which come with the type of tractorshown, the chains allowing the raising of the draw bar. This exampleshows the attachment used as a lister cultivator. Nu- .merous otherexamples of the utility of this attachment may be given, busters B maybe mounted on the end stub bars 7 after the yokes 30 have been removedand the other busters have been removed and the marking mechanism hasbeen removed. The two end busters would be used for digging furrows whenthe ordinary cultivating implement usually supplied ,wlth the type oftractor shown is used. These end busters would dig two furrows alongsideof the ground cultivatedfor the purpose of the retension of moisture inthe ground between the two furrows. The operator places his foot on theplate 26 so that when the attachment has a trip foot piece, the plate isjostled through the rod 24, thus informing the operator of this fact.The gist of the invention, however, resides 1n the subject matter of theappended claims. It is to be understood, therefore, that I do not wishto be limited to the examples shown and described herein except in asfar as I am limited by the claims, because it is apparent that numerouschanges in the details of construction, and in the combination andarrangement of parts may be resorted to without departing from thespirit or scope of the invention as hereinafter claimed.

In the for instance, two I The presentexamples of the invention haveproved highly practical and have therefore been given in detail sincethey attain the features of advantage enumerated as desirable in thestatement of the invention and the above description.

Having deseri ed my invention, what I claim as new is 1. An attachmentfor tractors' wherein the tractor includes a U-shaped pivoted drawbar;comprising a beam attached to the drawbar to extend transversely of thetractor in front of and in parallelism with the bight of the drawbar, aplurality of stub bars projecting rearwardly of the beam and thedrawbar.

means for raising and lowering the drawbar.

2. An attachment for tractors, wherein the tractor includes a U-shapedpivoted drawbar, comprising a beam, means for attaching the beam to thedrawbar in front of and in parallelism with the bight of the drawbar, aplurality of stub bars projecting rearwardly from the beam, a U-boltextending about one of the stub bars and through openings in the bightof the drawbar, and means for raising and lowering In testimony whereofI aflix my signature.
